' This invention relates to a newcovering or awning WhiCh,"in'itS features and appearance, constitutes a cross between roller awnings and fixed marquees. It-is a covering constituted essentially (but not necessarily) of rectangular rigid scales, panels, plates, slats, or section of thin material stiffened by means of beads, ribs or adequate frames, made of metal or of plastic material. Instead of being rolled in, the panelsare retracted substantially without friction, by means of the very practical device later described. Since the pieces of the covering are not subject to friction, the finishing of their surfaces is less subject to scratches and their durability is multiplied in comparison to that of rolled coverings; hence, their movement also become easy because the retraction may be done by means of-rollers instead of by friction means. The awning of the present invention, contrarily to the awnings made of canvas, may show fine effects as to shape and color, as well as durability, when made of steel, aluminum, and so on, and may be externally painted, enameled or coated with a durable and attractive protecting material in any of diiTerent known manners on the other hand, contrarily to metallic awnings,- this protection is permanent, sincethe covering is notexposed to any friction liable to cause damage to same.

The awning of the present invention has an external appearance, when distended, of an ample marquee with slightly offset parts, andwhen re-. tracted, of a narrow marquee or cornice which still offers protection. It has the advantage over the marquee in that the awning may be prefabricated. to a large extent, easily assembled and dismantled, and'reutilized, which renders it a movable product and an investment of.capital,.instead of representing an expense to the buyer. Italso has the advantage ,over the marquee of permitting adjustment of. light and shadow according to requirements, thanks to it natural movementand to its operating mechanism, to be later described, and which is designed to regulate the inclination or slope of the awning.

The primary object of the invention is to provide an awning structurewhich may, to a substantial extent, be prefabricated, which is readily operated to different positions, which iseasy to manufacture from various materials, and which gives an attractive and pleasing appearance.

v The following description covers, beyond the fundamental idea as to the method of fixing the panels of the covering, a method of and means for adjusting the inclination of the awning, and a possible system of control.

The improved awning constituting the subject of the present invention comprises a support made ie i e 9 f i ,1 pa el e g' ramswhi h cooperate, on top and on the sides with slides on which rest the panels of the covering secured thereto by pivoted claws or hooks and pins. The upper extension of one of the articulated rods nearest to the wall on which the awning is mounted is conveniently pivoted to the upper end of a slide rail along which may move rollers arranged at the lower end of another one of said rods. This same rod is connected, by means of two conveniently articulated rods, to a horizontal shaft movable by a lever, all in such a way that, when the lever is moved in one direction, the above-mentioned rollers move upwards along the rail, thus extending the support; and, when the lever is moved in the other direction, the rollers move down, retracting the support. The rollers are mounted on an end piece attached to a lower rod, the position of which, in relation to the lower rod, may be varied by means of removable pins, thus to increase or reduce the inclination of the awning. Helical springs, the tension of which may be adjusted by means of pins, are inserted in the rails forming the slides, and exert a compensating action to the movement of the awning structure. 1

The accompanying drawings illustrate an embodiment of the invention.

In the drawings:

Fig. l is a perspective view of an awning constructed in accordance with the invention, showing the supporting structure and the panels or slats, the awning being shown partly retracted and mounted on the side of a building;

Fig. 2 is a broken perspective view of the assembled awning, looking from below-toward one side, showing the position of the control lever, the awning in this view being shown extended;

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1 with parts broken away to show interior structure;

, Fig. 4 is a detail view partly in section showing the manner of attaching the panels or slats to the supporting lide rails; 1 Fig. 5 is a broken sectional view taken on the irregular line 55 of Fig.3, showing the structure of the forward part of the slide rail and cooperatingrollers; and

Fig. 6 is a broken horizontal sectional view taken on the line 6-5 of Fig. 3 showing the arrangement of the roller unit in the vertical slide.

The awning panels, plates or slats rest on a pair of spaced supports each constituted by two sets of rods I and 2, of sufficient mechanical strength and articulated together so as to form parallelograms, as shown in Figs. 1, 2', and 3. Rods l, which slope in a forward direction, are used in pairs and are shorter than the plain rods 2 which slope backwards. These rods 2 pass between pairs of rods I, to which they are articulated or pivoted by means of pins 3. The upper secured, to said end, a channel or U-shaped-end" piece 8, also having several holes 9, at its free end on which is mounted two rollers I5. These rollers, movable within the vertical channelslide. 5, are mounted'under a small platform It having on its lower part, standards 5 I provided with holes- In these holes, which correspond with or match the holes is of above-mentioned U-shaped piece 8, isinserted the axle M of rollers I5, platform If] becoming thus pivoted to piece 8. After the rollers are inserted into rail 4, their downward movement within same is limited by a pin rails 4 above the holes I9. This shaft 20 has a pawl 2| which is engaged by an operating or control lever 22 (Fig. 2). Said shaft is connected, by means of clamp 23 and, pivoted rods 24 and 25, to end piece 8 on the lower end of rod l, in such a way that rotary movement of shaft 26, produced by means of level 22, is transmitted to the rollers I5 which rise or fall along rail 4, thus opening or retracting the awning. To the upper ends of rods 2, a little above their points of articulation to the pairs of rods I, are secured, by means of pins 26, the longitudinal outwardly-extending rails or slides 2'i,'which, by virtue of the difference in length of rods I and 2, become staggered or onset one above the other, as shown in Fig. 3. These slides 21 have on their upper ends, fixed back claws or hooks .28 and on their lower ends pivoted front claws or hooks 29 to which are secured the panels, slats, or plates 32 having corresponding inwardly bent longitudinal edges 32a and $321), as shown in detail in Fig. 4. These panels, slats, or laminae are secured to the claws as follows: the back edge 32a of thelaminae, which is bent upwards and forward, is inserted in fixed hook 28 of the horizontal slide 2'! after loosening a pin 3| (Fig. 3) of the pivoted front hook. 29. This hook may be raised or pivoted on pin 36 and inserted in thefront downwardly-extending hookshaped edge 32b of thepanelas seen in Fig- 4. After this, the panel is pressed. down and pin 3| of the hook 29 is again put in position. This system permits an absolutely reliable and rapid attachment of the panels to the supporting structure. The upper panel at, which is in contact with the wall, is attached to angle brackets 35 by extending portion of the slides 21 are forked or include two spaced bar sections between which the upper end of the rOdS or bars 2 extend and to which they are pivoted by a pin 26, as shown in the lower portion of Fig. 5. The upper end of each slide, including the upper one, is'pivoted in this way, so that the pivot point is above the rods or bars I and below the rollers 42. The end of the I fill st l'od to whieh the upper slide 21 is pivoted, is

bolts 36, the angle brackets being rigidly secured to the railsjl by means of theupper bolts.5, as

. shown in, Fig. 3,.

llPWflIdi as Shown... The upper or backwardlybent toward the wall and pivoted between the sides'of the vertical slide 4 by a bolt 33 at a point above the'shaft-EU, as shown in Fig. 3. In the structure, as shown, each slide 21 is attached to the remaining structure by a pivot pin 26 at its upper portion and rests upon rollers 42 carried at the upper end of one pf the rods 2. This device ves h pl es 32 of h awn ng omens-P bi y of m em n e. e la es. af s cur t9 the horizontal slides can move only inthe d tion oi m ve n of thes des Tin 1 s awning will easily withstand the pressure oi wind, whether this pressure is exerted from be: low or from above said plates.

h end of e Dem aphic. ar s u i-t terms by pivoted rods I and 2 is constituted by two rods, 3,? and 38, Fi 1, on n e ch sideqof the two an d 2 and which ar vo ed o these s as to form greatly extended parallelograms. The up per ends of rods 31' and 38 are pivoted to a rod 39 parallel. to end r d 2 he, upp r nd of wh ch. bent upwardly, carries rollers ,42 similar to, the described rollers #22 carried by rods 2, and which supports the last longitudinal rod or slide. 2i.

The inclination of the awning is adjustable by means of the structure shown, in Fig 3,. by varying the position of piece 8 in respect to the'holes 6 in the first pair of rods I and the clamping piece I in holes 9 of piece 8.

The operation of the awning is readily effected. The operator acting upon level 22 in the appropriate direction impresses a rotation to the shaft 29. When this occurs, rod 25 is raised or lowered and, bymeans of rod 24, which is, pivoted to it, and pulls or pushes the lower end of the first pair of rods I and the member 8 provided with the rollers I5, raising or lowering the rollers I5 in the. slide 4, thus extending or retracting the panto raphic support.

The awning thus far described presents real advantages among which may be underlined'the parties, permitting 'at the sametime itsoperation from inside the buildingjitdesired, without the operator "having to expose himself to ra'my weather. F

The pantographic arm of the support is corn: pact and graceful, and presents a gradually increasing strength from the end to the basei s sembly is simple and is effected whollyby the use of prefabricated easily fitted parts'; the adjustable inclination allows user t correct the amount of i h or d w: stre ses areve rr small, since only rollingfriction prevails between the slides and supports, 7 5
